This is the first in a four-part series of posts covering the colorful homes on Cliffbourne Pl. NW, between Calvert St. and Biltmore St. You've seen these before, the green, yellow, red and blue homes, perfectly complementing each other. I imagine that I'm not the only one curious about the history of the four houses in this rainbow row of historic homes. So dive into the first home ... the one at 2515 Cliffbourne Pl. NW.
